Product Description

The Roadmaster 1129-131 is a 1-1/2-inch rear anti-sway bar kit from Roadmaster Suspension Solutions (RSS). An anti-sway bar links the left and right sides of the suspension to resist body roll, helping a large vehicle stay level and track more steadily in curves, crosswinds and uneven road conditions. Roadmaster anti-sway bars are designed as a custom fit for a specific chassis.

The bar is solid 4140 chromoly steel with polyurethane bushings. The kit includes an axle bracket adapter and mounting hardware; end links are not included.

Compatibility

Roadmaster anti-sway bars are chassis-specific. Contact us with your vehicle's year, chassis and GVWR so we can confirm fit before you order.
